I had some help on this the other day which was very useful but my project has changed a bit since then.
I have a container movieclip called cont_mc then inside that I have a series of pins which are called pin1_mc then inside the pins I have a final movie clip the size of the pin head to act as the hit state.
You can see what I talking about here:
Before I had the pins in the container movie clip I was able to bump them to the top of the display list using this code in the on over function.
Now I have wrapped them in the container mc this code no longer works and I get an error, must be a child of the caller?
How can I change this?
